T68 Synthetic Ultra Thermal Conductive Graphite Sheet
is a highly oriented pyrolytic graphite sheet known for its exceptional thermal conductivity. This advanced material effectively reduces the temperature of heat sources by rapidly spreading heat across its surface. With its ultra-thin, flexible design, T68 not only excels in heat dissipation but also offers superior EMI shielding.
T68 graphite sheets are produced through high-temperature hot pressing, resulting in a slightly thicker profile compared to other graphite sheets. Despite this, the material maintains remarkable thermal performance, with an XY-axis thermal conductivity reaching up to 1500 W/m•K. This outstanding in-plane heat transfer capability allows heat to disperse quickly and evenly, ensuring efficient cooling of electronic components.
The T68 Synthetic Graphite Sheet, produced through high-temperature hot pressing, offers exceptional heat conduction for small-sized products like mobile phones, wearable devices, 3C electronics, and displays. Lighter and thinner than traditional materials, it rapidly dissipates heat, making it ideal for devices requiring compactness and efficiency. Widely used in smartphones, tablets, and laptops, this advanced solution ensures optimal passive heat conduction and dissipation, enhancing product longevity and performance.
